Both were claimed by ISIL.
Concern has been heightened in Spain since the discovery on the 30th of December of a video of suspected jihadists in the centre of Madrid.
Two Spanish nationals were arrested and later released.
191 people died in March 2004 when militants planted bombs on trains at Madrid’s Atocha station.
